I did see a note stating that the overcenter spring needs to be removed.
Remember when cars were FUN?

Back in about 1970, I ran a Scheifer Rev-Lok diaphragm clutch that would stick to the floor at anything over 6K. The solution was to adjust the linkage so that there was only 30 thousands clearance between the disk and flywheel when the pedal was fully depressed. That made for about two inches of free play at the top. Solution to that was a really heavy spring to bring the clutch pedal up to the top so it felt like a normal clutch. No doubt the linkage could have been reworked to change the bellcrank ratios, but why bother. That diaphragm clutch had a really soft feel, but it locked up much better than the 3000 pound three finger clutch I had before.

McLeod diaphragm here and very happy with it. Ehrenberg recommends a diaphragm over the stock finger style on the street.

Let's try to say this without upsetting the purists. 1st of all, if the car needs to stay correct. No choice but to go Borg n Beck, it's proper.
Now onto the facts. All 3 finger set ups are old technology. The pedal has the most spring pressure at the wrong time, when it's released. The least amount when the clutch is engaged. So if the disc slips you need to add more spring pressure. What happens is you get a tiny bit more on the disc but mostly on your left leg.
A diaphram style places most of it's pressure on the disc while it's clamped. Basically it goes over center when it's released making the same pressure plate that can contain alot of power, easy to disengage.
Centerforce for me.
